A hilarious parody of coming attractions trailers and their excesses ensues. It stars Scrappy, Margie, Poopsie (Oopy with buck teeth), a dumb lion, and a chortling villain named Titan, The Terrible Twerp (delightfully voiced by Mel Blanc).
Everything on screen contradicts the narrator, who, at one point, just can't think of another superlative. Live action hands add a daisy to a putrid junkyard setting. Bold titles proclaim, "More Suspense And Very Much Expense!"
Margie
Titan corrects the narrator's pronunciation. Scrappy and Margie do impromptu impressions of John Barrymore and Greta Garbo.
The film breaks, so live action hands have to sew it up with needle and thread.
In closing, the narrator admits, "In as much as this is the most marvelous story ever told, the greatest cast ever assembled, and the most colossal production ever produced, we feel that no picture we might make could ever justify this description. We have decided not to make it. Besides, you've seen it, anyway."
